DAT Head Alignment tape mastered from a Sony PCM 2500 "reference" recorder which was "scope" aligned with a Sony Studio Prerecorded Music DDD master tape. The original Sony DAT alignment service tapes are no longer available, so to help out the DAT community keep this terrific format alive. I have created an alignment tape to help get your machine properly aligned so that you can play tapes that were recorded on other machines. I have tested my head alignment with tapes that were recorded on a Tascam DA30 and a Panasonic SV3800 and they all play fine on my machine. Included on the tape you have 1k test tones, 10k Test tone, Pink Noise , Pink Noise (Right channel inverted). Right , Left Center,Stereo and Noise Floor tests. There is also music to test the audio quality of your recorder. The tracks were recorded in 16bit/48k sound from a Digital to Analog Master using a Sony PCM D100 Recorder at around -20db to -10db levels so be sure to turn up your playback levels. All tapes were recorded in "real time" with brand new HHB DAT cassettes. Please use this tape to align your heads only. You can do this by adjusting your tape guide post until the audio is clear. Please be careful when using this tape as you can over align your tape causing your machine to eat your tape causing damage the tape. I will not be responsible for damaged tapes through physical abuse. All sales final. Please message me with your questions before purchasing.
